Abstract (en)
[origin: WO2018057446A1] Systems and methods of operating a refrigeration system including initiating a compressor shutdown operation (302), recording shutdown conditions (304), calculating one or more restart characteristics based on the recorded shutdown conditions (306), comparing the calculated restart characteristics with one or more compressor restart safety limits (308), when the calculated restart characteristics do not satisfy the restart safety limits, performing a temperature modulation pump down operation (310), and when the calculated restart characteristics satisfy the restart safety limits, completing the compressor shutdown operation (312).
